调试错误

Unable to create Debug Bridge: Unable to start adb server: adb server version (31) doesn't match this client (39); killing...
could not read ok from ADB Server
* failed to start daemon
error: cannot connect to daemon
'C:\download\soft\Android\android-sdk-windows\platform-tools\adb.exe start-server' failed -- run manually if necessary

 

 

解决办法：

查找被占用的端口：netstat -aon|findstr "5037" 

netstat -aon|findstr "5037"
  TCP    127.0.0.1:5037         0.0.0.0:0              LISTENING       1548
  TCP    127.0.0.1:5037         127.0.0.1:59769        ESTABLISHED     1548
  TCP    127.0.0.1:59769        127.0.0.1:5037         ESTABLISHED     9904

 

进入1548查看是哪一个应用：tasklist|findstr "1548"

找到以后杀死进程，进而解决问题。
